Scorpion Tuning Guide

Rig Tension

Tight, measured on Jib luff wire 250 lbs.

Jib Sheeting

With the jib pulled in tight, the continuation of the jib sheet from the fairlead to the clew should divide the front of the jib 45% up the luff wire. When over powered in heavy winds move the fairlead aft to flatten the jib and open the slot between the jib and the mainsail.

Spreaders

Length measured from the shroud to the side of the mast.

Check sweep back of spreaders by placing a straight batten from the port spreader tip to the starboard one. Measure from the centre of the batten to the rear of the mast.

Mast: M3, D, M7

Length: 320mm

Sweep Back: 110-130mm

To make the mainsail fuller swing the spreaders forward. To flatten the mainsail swing the spreaders aft.

Prebend

Check with jib only hoisted and the rig tension on.

Measure to a straight line between masthead and the black band at the gooseneck. All masts 25-30mm.

Spinnaker Pole Height

Check by hoisting a tape measure on the spinnaker halyard and measuring to the outer end of the spinnaker pole. For running in strong winds raise the pole, and for light winds lower the pole.

Standard Size: 3600mm
